Answer:
The chemical term in the equation for the precipitate of AgCl(s) is n=3.54*10^-3
Explanation:
the quantity of AgCl(s) in moles is:
n = 0.508g / 143.32 g/mol = 3.54*10^-3 mol
to verify it the mass of AgNO3 involved in the reaction should be
n AgNO3 required = n = 3.54*10^-3 mol
the mass of n involved should be higher than n AgNO3
n existing = V*N = 0.523 mol/L * 35*10^-3 L = 18.305*10^-3 mol
As the intermolecular forces get weaker, the amount dissolved decreases. Ammonia can form hydrogen bonds with water thus allowing it to be more soluble. CO2 and O2 can only react through London forces, but since CO2 has a higher molecular mass, more electrons, it will have a larger in magnitude temporary dipole moment. This results in the CO2 being more soluble in water than O2.
The overall trend in solubility is NH3>CO2>O2
Answer:
The mole fraction composition of the liquid is :
Mole fraction of butane, pentane and hexane are 0.3638,0.3908 and 0.2454 respectively.
Explanation:
Mass of the liquid mixture = 200 g
Percentage of butane = 30%
Mass of butane = 
Moles of butane = 
Percentage of pentane= 40%
Mass of pentane= 
Moles of pentane= 
Percentage of hexane = 100% - 30% - 40% = 30%
Mass of hexane =
Moles of hexane = 
Mole fraction of butane, pentane and hexane : 
<span>After four half-lives 0.1 mole of the radioactive isotope would remain. If the amount of the isotope that remains after each half life is one half of previously existing amount. Half of 1.6 equals 0.8, half of 0.8 equals 0.4, half of 0.4 equals 0.2, and finally half of 0.2 equals 0.1 mole.</span>
